When the correspondence between each character code and each character is a correspondence set by a user or a manufacturer, the input method used by the user needs to be changed correspondingly to ensure that the finally obtained target character is matched with the character content of the data input by the user through the input method.
It should be noted that the correspondence between each character code and each character is not limited to the correspondence between a chinese character and its character code, but may also be the correspondence between a japanese character and its character code, or the correspondence between a russian character and its character code. It is understood that chinese, japanese and russian are only three expressions of the correspondence between each character code and each character, and do not represent only the three expressions.
S11: and establishing a capture function according to the screen-on function.
In this embodiment of the present application, S11 is specifically configured to obtain a calling convention and a return value type of the screen-up function, and establish the capture function according to the calling convention and the return value type, so as to obtain the text codes included in the parameters of the screen-up function by using the capture function.
In order to improve the application range of the input data acquisition method, the screen-on function comprises the following steps: ImmGetComositionStringW or CRange:SetText.
It should be noted that most Input methods are currently configured based on an Input Method Manager (IMM) or a Text Service Framework (TSF), and therefore, the screen-up function includes imgetcompositionsstringw corresponding to the IMM and CRange:: SetText corresponding to the TSF.
It is understood that when the input method is constructed based on other architectures, the function of the architecture for realizing display of input data can be acquired as the screen-on function.

classifying the corresponding relation according to the character category;
acquiring a character coding range corresponding to each category;
acquiring a target character coding range of the target character coding;
determining the target character corresponding to the target character code according to the corresponding relationship, specifically:
and under the condition that the target character coding range is matched with the character coding range corresponding to the target category, determining the target characters according to the target corresponding relation corresponding to the target category.
8. An input data acquisition apparatus, comprising:
the construction module is used for constructing the corresponding relation between each character code and each character in advance;
the first establishing module is used for establishing a capturing function according to the screen-on function;
the first acquisition module is used for acquiring a target character code which is contained in the screen-loading function and corresponds to the input data through the capture function under the condition that the screen-loading function executes the screen-loading operation of the input data;
the first determining module is used for determining the target characters corresponding to the target character codes according to the corresponding relation;
the screen-up function is specifically a function for displaying the input data, and the screen-up operation is specifically an instruction operation for displaying the input data.
9. An input data acquisition apparatus, comprising:
a memory for storing a computer program;
a processor for implementing the steps of the input data acquisition method according to any one of claims 1 to 7 when executing said computer program.
10. A computer-readable storage medium, characterized in that a computer program is stored thereon, which computer program, when being executed by a processor, carries out the steps of the input data acquisition method according to one of claims 1 to 7.
